really good , great price
Buena calidad, agujeros totalmente metalizados.
O produto atendeu nossas expectativas e nos foi muito útil em nosso projeto
AOK
Not yet got around to testing but appears to be useful, however be warned it does not attach to the main unit unless Battery/Back is completely removed in which case you will need to source your own power
Fine Proto Board for Experimets with M5Stack
super seller very good perfect quality fast fast fast fast
Interesting if like me, you DIY modules.
I bought a couple of proto modules and I realised later that there was no female connector on the backside of the proto module ! Is this correct ? Very problematic if you want to stack the modules: The pictures on Banggood web site are correct, but I would have prefered there would be some connectors to solder as not easy to buy ! Picture shows how backside should be !
Worls great
